[dpdk-dev] [PATCH] mk: fix pcap build with empty LIBPCAP_CFLAGS

[Robert Sanford]

Fix pcap build - In rte.sdkbuild.mk with CONFIG_RTE_LIBRTE_PMD_PCAP=y,
we error-exit if LIBPCAP_CFLAGS is empty. On some distros (e.g., Centos
6.4),
it is normal for "pcap-config --cflags" to output only a newline, because
pcap
header files reside in /usr/include/.
Solution is to remove the line that checks whether LIBPCAP_CFLAGS is empty.
